Title: Improvements in yielding members such as valve tappets and shock absorbers
IPC: F01L1/16
Filed: 1954-05-17
Abstract: 755,047. Dashpots. PIERCE, D. H. May 17, 1954, No. 14397/54. Class 108 (3). [Also in Group XXVII] A yielding member, such as a shock absorber, comprises a cylinder 16 with a plunger 18 therein through which passes a stem 22 carrying at one end a valve 24, operating with a movable seat 42 and at the other end a second plunger 26 engaged by a spring 30 forcing the plungers 18, 26 apart, and the space between the plunger 18 and the end of the cylinder 16 is filled with a hydraulic fluid or with a material, such as the silicone composition known as "bouncing putty", which is resistant to sudden deformation but freely fluid under sustained pressure. In the drawing the yielding member comprises a tappet 12 in the valve gear of an internalcombustion engine. When a sudden force is applied to the bottom of the cylinder 16, the hydraulic fluid or " bouncing putty" in the space 40 below the valve head 24 and seat 42 remains substantially rigid, a small amount thereof being forced through a small clearance at the edge of the ring 42 to cause slight contraction of the member. When the force is removed, the spring 30 moves plunger 26 upwards to take up any clearance, the fluid or putty flowing freely around the valve 24 which is moved off its seat 42. When the clearance has been taken up the seating ring 42 is moved up by the spring 44 to re-engage the valve 24. The separation of the plungers 18, 26, is limited by contact of a shoulder 32 on the stem 22 with a flange 34 on the plunger 18.

Patent GB-843575-A (GB)
Title: Production of glycidyl polyethers of polyhydric phenols
IPC: C08G59/06
Filed: 1958-05-09
Abstract: Glycidyl polyethers of polyhydric phenols are produced by reacting a polyhydric phenol with more than a stoichiometric amount of epihalohydrin under substantially anhydrous conditions in the presence of a quaternary ammonium compound to form the corresponding halohydrin ether and then dehydrohalogenating said ether.  Although the principal product is the monomeric polyether (see Group IV(b)), as much as 20% by weight of the product may comprise essentially high molecular weight polymers.  The polyhydric phenols include mono-, di or polynuclear polyhydric phenols (including phenol-aldehyde poly condensates) which may contain alkyl, aryl or halogen ring substituents and the phenol rings may be joined by alkylene or sulphone groups.  In examples, bis(4-hydroxy phenyl) dimethylmethane and epichlorhydrin are reacted in the presence of tetramethyl ammonium chloride or benzyl trimethyl ammonium chloride and are subsequently dehydrohalogenated with NaOH to produce a monomeric glycidyl polyether together with essentially high molecular weight polymers; the glycidyl polyether product was hardened by mixing with 4, 41-methylene dianiline and curing for 20 hours at 85 DEG C. and thereafter annealing for 3 hours at 160 DEG C. Specifications 666,732, 787,091 and 788,556 are referred to.ALSO:Monomeric glycidyl polyethers of polyhydric phenols are produced by reacting a polyhydric phenol with more than a stoichiometric amount of epihalohydrin under substantially anydrous conditions in the presence of a quaternary ammonium compound to form the corresponding halohydrin ether and then dehydrohalogenating said ether.  It is preferred to use at least 3 moles of epihalohydrin per mole of phenolic hydroxyl group.  The preferred epihalohydrin is epichlorohydrin.  The term polyhydric phenols includes mono, di- or polynuclear polyhydric phenols and polyphenylols such as are obtained by condensation of phenols and unsaturated aldehydes, and the phenols may contain alkyl, aryl or halogen ring substituents and the phenol rings may be joined together by alkylene or sulphone groups.  The reaction of the phenol and epihalohydrin is preferably conducted at temperatures not exceeding 60 DEG C. in the presence of 0,01 to 0,05 mole of quaternary ammonium compound per each phenolic hydroxylic group. Excess epihalohydrin is conveniently removed using standard low pressure, short contact time distillation techniques.  The dehydrohalogenation is preferably carried out continuously using 5-20% excess of the stoichiometric amount, of a base (e.g. sodiumor potassium hydroxide) in a liquid medium comprising a volatile, water soluble alcohol or ketone and a hydrocarbon or ether.  It is advantageous to add the base in two steps. Temperatures between 40 DEG  and 70 DEG C. may be used for the dehydrohalogenation.  The organic solvent may then be stripped from the product under reduced pressure and recycled to the process, the glycidyl polyether being finally stripped under vacuum at 150 DEG C.  Specifications 666,732, 787,051 and 788,556 are referred to.
